Final answer:
Daniel's speed is calculated by dividing the distance he runs, 105 kilometers, by the time it took, which is 3 hours. Therefore, his speed is 35 kilometers per hour (km/h).
Step-by-step explanation:
Daniel runs 105 kilometers in 3 hours. To find his speed, we divide the total distance by the total time. Speed is calculated by the formula: Speed = Distance ÷ Time.
Using the formula:
- Distance = 105 km
- Time = 3 hours
- Speed = 105 km ÷ 3 h = 35 km/h
Daniel's speed is
35 kilometers per hour (km/h).
This same method is used to calculate average speeds in various scenarios, such as for a car trip or a train journey, by dividing the distance traveled by the time taken to travel that distance.
